I think Sam says this every other year... "I'm going to write it soon."
And then next year he comes out with Darkman IV or signs on to direct the remake of Krush Groove. Just watch.

No, not the remake. An honest-to-goodness Sam Raimi fourquel. As per Bleeding Cool, the brothers Raimi are planning on writing the script this summer.
Now, they may not end up coming up with a script that they like, so this is extremely tentative. Nonetheless, it's hard not to speculate irresponsibly (and play with Photoshop) anyway. If the remake works, we could have a very unique situation of two simultaneous Evil Dead franchises in different realities...and then get Bryan Singer to combine them both somehow. Just kidding.
I hope.
